I own a vanson custom suit but I lost weight so it is loose. I need to send it out to get resized. I am a memeber at harris hill race way in san marcos tx so I get to do 4 to 5 track days a month. If you live near Austin or San Antonio you got to join us 200.00 a month for 5 track days a month sick deal. I needed a suit to use while I get the vanson recut so I called stg gave them my size 5'9 220lbs 47 inch chest right not skinny. lol. They recommened this suit. I ordered it and had it in 3 days love stg. I figured it would fit ok but what a surprise the xxl fit me better then my custom siut new, It was perfect with a back protector tight in all the right places but still able to move around the bike. As far as protection I use a hit air vest so it is more then enough but if I knew how good it fit I would have bought the better cortech suit for 799.00. I like this suit so much I am not sending the vanson out to be resized because I plan on riding in this suit for a while, If it does not hold up in a crash I will resize the vanson or upgrade the cortech but the quality seems very good for now, If you are built like me not thin buy this suit it fits perfect.
